Latest builds r31363 on Windows, r31370 on Mac PPC don't open links in new windows/tab when asked for; only on a particular website.
According to my preferences, a middle-click an a link the open it in a new tab.
Check the URL : http://www.clubic.com/forum/debat-sur-l-actu/
It's the forum of one of the most-visited IT-related french website. (4.3 million unique visitors/month)
When you middle-click on a link (i.e the thread title on the forum), it functions as intended: the link is opened in a new tab.
When you middle-click on the small orange square left to a link (which brings you to the first unread message in the thread), the link is opened in the very same page.
IE, Firefox aren't affected...
Weird things appear sometimes.
1 - Load http://www.clubic.com/forum/debat-sur-l-actu/
2 -middle-click on an orange square
3 - link opens in the same window -> bug
2 - Load http://www.clubic.com/forum/debat-sur-l-actu/
3 - Reactivate JS
4 - middle-click on an orange square
5 - Hurray !! link opens in another window/tab
I would like to help further but really don't know how.
